Autocomplete - provide reference to the parent component in displayFn

feature request:

in displayFn, the this refers to the Mdautocomplete component, not to the custom component in which displayFn is implemented. For translation, I need to grab a translationServive which is injected onto my custom component. My current implementation is kind of a hack:

    displayFn(enumValue: any): string {
        // this here is acually the Mdautocomplete control
        // HACK to get the AutocompleteEnumFormFieldComponent
        const that = (<any>this).template._parentView.parent.component;
        const translatedValue = that.translateService.instant(enumValue);
        return translatedValue;
    }

You can bind your displayFn to the component with:

[displayWith]="displayFn.bind(this)"

Then you can use this.translateService… without the hack!
